Abstract: 957,926. Sheet metal feeds. HORDERN, MASON & EDWARDS Ltd. Feb. 15 1963, [Jan. 30, 1962], No. 3885/62. Heading B3W. An intermittent roller feed mechanism is characterized in that the feed rollers comprise a plurality of relatively narrow elements which are axially adjustable to suit the width of the stock or the position of unworked longitudinally extending zones thereof. In order to reduce the inertia of the feed roller assembly the lower feed roller comprises narrow elements 21 which are slidable along a shaft 23 and clamped to it by cotters. The shaft 23 is driven through a freewheel 60 by a gear 44 which is intermittently rotated by a quadrant 43, actuated by a push rod 40 and variable throw eccentric. Secured to the shaft 23 is a gear 50 which drives the upper feed roller 22, and there is also a brake 64. The roller 22 runs on a shaft 24 mounted in pivoted brackets 28 which can be raised by a hand control 65. In the case of elements 21 intended to run at the edge of the stock, they may be provided with flanges to guide the stock. In a modification the stock engaging elements may be merely rings supported by internal bearings on a fixed shaft and driven through gear teeth formed on the rings.

Abstract: 229,658. Cheron, J. J. Feb. 21, 1924, [Convention date]. Self-feeding brushes; brushes combined with scrapers; bristles, fixing. - The main body 1, Fig. 2, of the brush is formed with water-outlet conduits 28, 11 leading from a bore 2 in which is fitted a hollow handle 3 connected to a source of water supply and adapted to slide longitudinally to control the flow of water through the conduits. A number of brush elements 4 are secured to the body 1 by means comprising a casing 5 co-operating with a star-shaped nut 8, which is apertured at 9 and is screwed to the body 1. The handle 3 is yieldably secured to the body through the medium of a helical spring 15, a socket 12, and a bayonet slot or other connection between socket and the body. The handle is formed with apertures 26, 29 so placed that in the normal position of the handle, water flows to the brush elements by way of the aperture 29 registering with the conduit 11 and is prevented from flowing through the aperture 26 by an apertured packing 27. Longitudinal movement of the handle, which is guided by a pin-and-slot arrangement, is obtained by means of a lever 19 pivoted on the handle and adapted to bear against an adjustable nut 24 on a rod 21 secured to a boss (not shown) on the body 1. On actuation of the lever, the aperture 29 is moved out of registration with the conduit 11 and the end of the handle is withdrawn from the packing 27 allowing liquid to escape through aperture 26, 28 on to the surface being cleaned. A scraper may be provided adjacent the aperture 28. In the construction shown in Fig. 4, the discharge of water can be stopped without stopping the supply to the hollow handle. The end of the handle is provided with a valve 33 which is adapted to close the aperture 26 when the handle is withdrawn sufficiently far from the body 1. The aperture 29 is then out of registration with the conduit 11. The body 1 may be moved relatively to the handle by means as employed in the construction shown in Fig. 2, but is preferably moved directly by hand, being maintained in different positions by means of recesses 37, 38, 39 therein which are engaged by a stud 35 on a resilient arm 36 secured to the handle 3.

Title: Improvements in and relating to the purifying of organic dyestuffs
IPC: C09B67/54
Filed: 1947-02-13
Abstract: Organic acid dyestuffs contaminated by inorganic salts are purified by making a saturated solution of the dyestuff in a solvent which will also dissolve the inorganic salts, filtering off any remaining solid matter, adding to the filtrate a precipitant for the inorganic salt, and again filtering.  The solvent may be water, an ether of ethylene glycol or diethylene glycol, an ethanolamine, diacetone alcohol, furfuryl alcohol, tetrahydrofurfuryl alcohol, or a homologue of aminopropanol.  The precipitants may be a mixture of an alcohol and an aromatic compound, (e.g. 2 mols. methanol to one vol, tuluol) or may contain propyl alcohol, benzene, furfuryl alcohol, naphtha, or xylol.  Examples describe the purification of (1) Chromolar Yellow NGR, using carbitol as solvent and a methanol-toluene mixture as precipitant; (2) Fast Light Orange R, using ethylene glycol monoethyl ether as solvent and an ethanol-benzene mixture as thinner; (3) Azo Yellow A5W, using furfuryl alcohol as solvent and a propyl alcohol-xylol mixture as thinner.  A diagrammatic drawing of a conventional assembly of apparatus is provided, in which the crude dye is dissolved at elevated temperature, and after the first filtration precipitation, and second filtration stages, the purified dye solution is evaporated on a drum drier, and the solvent and precipitant recovered and fractionated.
